All  of  the  samples  examined  fully  met  their  guaranties  and 
all  were  of  average  quality. 

The  cost  of  nitrogen  in  these  samples  ranged  from  about  29  to  35 
cents  per  pound,  the  average  being  31.5  cents. 

Nitrate  of  soda  has  been  a  relatively  cheap  source  of  fertilizer 
nitrogen  this  year.  The  nitrogen  in  it  is  more  quickly  and  com- 
pletely available  to  crops  than  nitrogen  from  any  other  com- 
mercial source.     As  a  spring  top-dressing  on  grass  land  and  on

58  CONNECTICUT   EXPERIMENT   STATION   BULLETIN   217. 

winter  grain  which  has  suffered  some  winter-kiUing,  as  well  as 
a  source  of  nitrogen  in  home  mixtures,  nitrate  of  soda  deserves 
more  attention  and  use  than  it  has  received  from  farmers. 

The  figures  gathered  by  the  Bureau  of  Soils  at  Washington 
indicate  that  about  29  per  cent,  of  the  nitrogen  in  the  mixed  fer- 
tilizers made  in  1918  was  in  form  of  nitrate  of  soda,  16  per 
cent,  in  form  of  sulphate  of  ammonia  and  the  balance,  about  55 
per  cent.,  in  organic  forms.  These  percentages  probably  will 
change  with  changes  in  the  relative  cost  of  the  three  forms  of 
nitrogen. 

The  price  of  nitrate  in  Chili  is  fixed  by  what  is  bid  in  the 
London  market.  During  the  war  the  demands  for  the  manu- 
facture of  munitions  and  the  scarcity  of  shipping,  high  insur- 
ance rates,  etc.,  caused  nitrate  to  advance  sharply  in  price  and 
then  to  disappear  from  the  market.  At  this  writing,  November, 
1919,  the  wholesale  quotation  is  $58  per  ton  which  should 
represent  a  retail  price  of  about  $70. 

SULPHATE  OF  AMMONIA. 

Only  a  single  sample  was  examined. 

12560.  Sold  by  the  Barrett  Co.,  New  York  City.  Stock  of 
Berkshire  Fertilizer  Co.  Cost  $100  per  ton.  It  contained  20.9 
per  cent,  of  nitrogen.  Nitrogen  in  this  article  therefore  cost  23.9 
cents  per  pound,  which  is  the  cheapest  source  of  nitrogen  that 
has  been  in  our  market  this  year. 

COTTON  SEED  MEAL. 

Ninety-five  samples  of  meal  bought  for  use  as  a  fertilizer 
have  been  examined. 

Seventy-six  of  them  met  their  guaranteed  compositions  and 
need  no  further  notice  here.  Seventeen  failed  to  meet  their  guar-" 
anties  and  their  analyses  appear  in  the  following  table. 

The  average  percentage  of  nitrogen  in  the  95  samples  exam- 
ined was  5.97  and  the  average  ton  cost,  in  car  lots,  $63.21. 

The  average  nitrogen  content  of  the  samples  which  met  their 
guaranty  was  6.1 1  per  cent.;  the  average  of  those  which  failed 
to  meet  their  guaranties  was  5.71  per  cent. 

Cotton  seed  meal  contains  about  2.9  per  cent,  of  phosphoric 
acid  and  1.9  per  cent,  of  potash. 


CASTOR  POMACE.  59 

These  ingredients  are  not  guaranteed  and  are  disregarded  in 
sales.  Charging  the  cost  of  meal  wholly  to  nitrogen,  the  average 
cost  per  pound  of  nitrogen  has  been  53  cents. 

If  the  phosphoric  acid  in  the  meal  is  credited  at  6  cents  and  potash 
at  30  cents,  the  average  cost  of  nitrogen  as  shown  by  our  analyses  has 
been  40.5  cents  per  pound. 

The  average  figures  for  the  past  seven  years  are  as  follows: 

Number  Cost  per  Per  cent.  Nitrogen  costs 

Year.  analyzed.  ton.  nitrogen.         cents  per  pound.

1918  S6  57-41  S.98  36.0 

1919  95  63.21  5-97  40.5 

There  has  been  a  yearly  rise  in  the  average  price  of  cotton 
seed  meal,  amounting  to  91  per  cent.,  a  yearly  decrease  in  the 
amount  of  nitrogen  amounting  to  13  per  cent,  and  in  consequence 
the  actual  cost  per  pound  of  nitrogen  has  increased  nearly  95 
per  cent.  At  this  writing,  November  19 19,  cotton  seed  meal  is 
quoted  in  New  York  at  $70  to  $75  per  ton. 

As  evidence  of  the  economic  confusion  wrought  by  the  war, 
it  is  stated  that  Egypt  has  85,000  tons  of  meal  for  which  there 
is  no  home  demand  and  no  shipping  available  to  transport  it. 

Coal  on  the  other  hand  is  hard  to  get  at  $80  per  ton  in  that 
country  and  cotton  seed  cake  is  being  used  for  heating,  i^ 
tons  of  cake  is  said  to  be  the  equivalent  in  heating  power  of 
one  ton  of  coal. 

There  appears  to  be  no  present  prospect  of  cheaper  cotton 
seed  meal  in  the  market. 

Under  the  new  fertilizer  law  cotton  seed  meal  is  classed  as  a 
commercial  fertilizer  and  is  subject  to  the  same  requirements  as 
any  other  fertilizer. 

CASTOR  POMACE. 

Four  samples  were  analyzed  as  follows: 

12730.  Sold  by  American  Agricultural  Chemical  Co.,  New 
York  City.     Stock  of  W.  Howard,  Windsor. 

12732.  Sold  by  Apothecaries  Hall  Co.,  Waterbury.  Stock  of

The  cost  of  available  phosphoric  acid  in  this  form  has  ranged  from 

7.9  to  14.2  cents  per  poimd,  an  average  of  10.5  cents.  It  has  cost  about 

one  cent  a  pound  more  in  the  14  per  cent,  goods  than  in  the  16  per 
cent. 


PHOSPHATES.  65 

The  average  prices  given  in  our  reports  for  the  last  8  years 
are  as  follows : 

1912  5.6  cents 

1913  4-7 

1914  4-65 

1915 3-99 

1916  6.7 

1917  6.2 

1918 7-9 

1919  10.5 

The  price  of  acid  phosphate  has  advanced  almost  to  prohibitive 
prices  in  spite  of  the  fact  that  oil  of  vitriol,  which  combined 
with  lime  makes  up  about  half  the  weight  of  acid  phosphate,  has 
declined  in  price  since  the  armistice.  Various  contributing 
causes  have  been  brought  forward  to  explain  the  facts :  The 
increased  cost  of  labor  and  of  freight,  the  scarcity  of  shipping 
to  bring  the  rock  to  northern  factories,  a  strike  at  the  phosphate 
mines  which  has  for  a  time  stopped  the  output  of  rock  phosphate, 
car  shortage  and  the  indisposition  of  manufacturers  to  sell 
farmers  anything  other  than  ready  mixed  fertilizers  at  a  reason- 
able price.  The  practice  of  selling  acid  phosphate  on  condition 
that  a  certain  amount  of  mixed  fertilizer  is  sold  with  it  is  an 
unfair  and  illegal  practice  under  the  laws  at  present  in  force. 

The  effect  of  this  situation  is,  in  our  judgment,  to  increase 
the  sales  of  raw  phosphates,  ground  apatite  mixed  with  barium 
sulphide,  Tennessee  floats  and  fine  ground  soft  Florida  rock, 
rather  than  to  increase  the  use  of  factory  mixed  goods,  and  to 
the  trial  of  all  possible  home  mixtures  to  increase  the  availability 
of  these  slower  acting  forms  of  phosphoric  acid. 

From  the  preceding  discussion  we  may  put  together  the  approx- 
imate cost  per  pound  of  phosphoric  acid  in  those  articles  in 
which  phosphoric  acid  is  the  chief  fertilizing  ingredient. 

Total  phosphoric  acid 

In  barium-phosphate  5-7-7-S 

Florida  soft  phosphate  9.1 

Available  phosphoric  acid 

Acid  phosphate  10.5 

Basic  lime  phosphate 8.7-9.8 

Precipitated  bone  phosphate 8.0 

At  these  prices  certainly  precipitated  bone  phosphate  has  been 
the  best  purchase,  price  and  fertilizing  value  considered. 


66  CONNECTICUT   EXPERIMENT    STATION    BULLETIN    217. 

Considering  the  relative  cost  of  "available"  phosphoric  acid 
and  the  two  forms  of  less  soluble  phosphoric  acid,  it  is  quite 
certain  that  on  our  light  humus-poor  soils  and  for  the  variety 
of  crops  generally  grown  in  the  state  the  more  soluble  forms  at 
present  prices  are  preferable. 

III.     RAW  MATERIALS  OF  HIGH  GRADE 
CONTAINING  POTASH. 

COTTON  HULL  ASHES. 

Three  samples  were  analyzed  as  follows : 

12480.  Sold  by  Olds  &  Whipple,  Hartford.  Stock  of  John 
Wolf,  Windsor.  Cost  $6  per  unit  of  water-soluble  potash, 
equivalent  to  30  cents  per  pound  for  actual  potash.  It  contained 
29.30  per  cent,  potash. 

12654.  Sold  by  Olds  &  Whipple,  Hartford.  Stock  of  John 
Wolf,  Windsor.  Cost  $6  per  unit  of  water-soluble  potash, 
equivalent  to  30  cents  per  pound  for  actual  potash.  It  contained 
19.10  per  cent,  of  potash. 

12902.  Sold  by  Olds  &  Whipple,  Hartford.  Stock  of  New 
England  Tobacco  Corp.,  John  Wolf,  manager,  Windsor.  Cost 
$4  per  unit  of  water-soluble  potash,  equivalent  to  20  cents  per 
pound  for  actual  potash.     It  contained  25.70  per  cent,  of  potash. 

Sample  12480  was  sold  in  March.     The  price  of  12902,  sold  by 

the  same  firm  three  months  later,  reflects  the  falling  price  of 

potash. 

POTASH  SALTS. 

The  following  analyses  show  the  composition  of  potash  salts 
from  various  sources,  probably  all  of  them  American.  They 
were  not  taken  from  stock  on  sale  in  this  state,  but  were  con- 
tributed chiefly  by  Prof.  Whitney,  chief  of  the  U.  S.  Bureau 
of  Soils :

POTASH    SALTS.  67 

The  Searles  Lake  potash  contains  borax  in  considerable 
amount.  A  very  large  amount  of  borax  in  a  fertilizer  may 
cause  injury  or  ruin  to  crops.  The  U.  S.  Department  of  Agri- 
culture, acting  under  authority  conferred  during  the  war,  has 
ordered  manufacturers  not  to  sell  fertilizers  containing  more 
than  0.1  per  cent,  borax  without  plainly  showing  the  amount  of 
borax  on  the  containers. 

The  following  samples  were  taken  in  the  Connecticut  market: 

12485.  American  Potash.  Sent  by  Prof.  W.  L.  Slate,  Jr., 
Storrs,  Conn.     It  contained  52.36  per  cent,  of  potash. 

12509.  Antioch  Nebraska  Potash.  It  contained  22.18  per 
cent,  of  which  4.41  per  cent,  was  muriate  and  17.77  P^^  cent, 
sulphate. 


OTHER  MATERIALS  CONTAINING  POTASH. 

12029.  Alpha  Potash-Lime  Fertilizer.  Made  by  Alpha  Port- 
land Cement  Co.,  Easton,  Pa.  Sent  by  E.  N.  Austin,  Suffield. 
It  contained  2.33  per  cent,  of  potash  and  25.92  per  cent,  of  lime. 
Cost  $13  per  ton, 

12568.  Alpha  Potash-Lime  Fertilizer.  Made  by  Alpha  Port- 
land Cement  Co.,  Easton,  Pa.  Stock  of  Louis  H.  Porter, 
Stamford.  Guaranteed  2.50  per  cent,  potash.  It  contained  2.17 
per  cent,  potash.     Cost  $12  per  ton. 

If  potash  is  valued  at  30  cents  per  pound,  the  price  current  in 
the  spring  of  19 19,  the  valuation  of  the  potash  alone  about  covers 
the  cost  of  the  fertilizer. 

Wood  ashes  have  been  used  considerably  as  a  source  of  potash 
on  the  tobacco  crop  being  bought  at  $6  to  $6.30  per  unit  of 
potash  which  is  equivalent  to  30  to  323^  cents  per  pound. 
Analyses  of  wood  ashes  are  given  on  later  pages  of  this  report. 

NITRAPO. 
.  With  the  potash  salts  may  be  classed  this  material,  offered  by 
the  Nitrate  Agencies  Co.  of  New  York  City.     It  is  stated  to  be 
a  product  of  refineries  in  Chili. 

12703.  Sent  by  the  Hartford  county  agricultural  agent.  It 
contains  14.52  per  cent,  of  nitrogen  and  19.94  per  cent,  of  potash. 
It  contains  less  than  one-half  per  cent,  of  chlorine  and  no 
borax.  The  price  quoted  is  $175  per  ton  in  New  York.  Allow- 
ing 31^^  cents  per  pound  for  nitrogen  the  potash  costs  41.3 
cents  per  pound  or  $8.26  per  unit.

FISH  MANURES. 

Fifteen  analyses  of  this  material  appear  in  the  table.  In  only- 
one,  12841,  is  the  nitrogen  less  than  was  guaranteed  but  four 
failed  to  meet  the  guaranty  of  phosphoric  acid. 

13509  is  fish  bought  in  the  previous  year. 

The  six  other  samples  of  which  the  prices  are  given  and  the 
composition  is  normal  have  the  following  average  composition: 

Nitrogen 8.36 

"Available"    phosphoric  acid  7.45 

Insoluble  phosphoric  acid 3.04 

Cost  per  ton $101.00 

If  the  "available"  phosphoric  acid  is  valued  at  lo^  cents  per 
pound,  its  cost  in  acid  phosphate,  and  the  insoluble  phosphoric 
acid  at  4  cents,  the  average  cost  of  nitrogen  in  fish  manures  has 
been  about  49.6  cents  per  pound.

SLAUGHTER  HOUSE  TANKAGE. 

Of  the  seven  samples  drawn  by  the  station  six  represent 
products  low  in  nitrogen.     (For  analyses  see  page  70.) 

The  three  samples  from  Meriden,  made  by  C.  M.  Shay  Co., 
are  much  below  their  guaranty  of  nitrogen. 

If  the  phosphoric  acid  in  these  samples  is  valued  at  6  cents,  the 
average  cost  of  nitrogen  is  about  42.1  cents.  If  on  the  other 
hand  nitrogen  is  reckoned  worth  49.6  cents  per  pound,  as  in  fish 
scrap,  the  phosphoric  acid  costs  4.1  cents.

BONE  MANURES. 
(Analyses  on  page  72.) 

All  of  the  sixteen  brands  examined  substantially  meet  their 
guaranties.  In  twelve  brands  more  than  50  per  cent,  of  the  bone 
was  finer  than  1-50  inch. 

The  average  cost  of  all  the  brands  was  $58.27  per  ton.  If 
nitrogen  is  given  a  value  of  49.6  cents  a  pound,  as  in  cotton 
seed  meal,  a  pound  of  phosphoric  acid  cost  5.2  cents. 

If  phosphoric  acid  is  valued  at  6  cents,  nitrogen  costs  43.8  cents. 


Following  is  a  statement  of  the  approximate  average  prices 
which  have  been  paid  in  this  state  for  nitrogen,  phosphoric  acid 
and  potash  during  the  spring  of  19 19.

Comparing  brands  containing  the  same  amount  of  available 
phosphoric  acid  but  different  amounts  of  nitrogen,  it  is  possible 
to  approximately  determine  the  average  cost  price  of  nitrogen. 
Thus  II  brands  with  10  per  cent,  available  phosphoric  acid  con- 
tain 0.82  per  cent,  and  cost  $41.14;  19  contain  1.65  nitrogen  and 
cost  $49.77;  .82  per  cent,  or  16.4  lbs.  of  nitrogen  in  the  ton 
cost  $49.77  —  $41.14  =  $8.63  ^  16.4  =  52  cents  per  pound  for 
nitrogen.  Rising  from  a  guaranty  of  1.65  per  cent,  nitrogen  to 
2.47  per  cent,  nitrogen  costs  32.3  cents.  Rising  from  2.47  per 
cent,  to  3.29  per  cent.,  nitrogen  costs  36.4  cents. 

It  is  clear,  as  has  always  been  contended  by  the  station,  that 
the  higher  grade  fertilizers,  notwithstanding  their  higher  price, 
are  the  more  economical.

Guaranties. 

Fifteen  samples  contained  less  nitrogen  than  was  guaranteed, 
and  12  contained  less  phosphoric  acid. 

In  most  cases,  however,  the  money  value  of  the  deficiency  in 
one  ingredient  was  made  good  by  an  overrun  in  the  other. 

Eight  samples  failed  to  thus  make  good  by  the  amounts  given 
below,  valuing  nitrogen  at  45  cents  per  pound  and  available  phos- 
phoric acid  at  10  cents.

But  of  Armour's  Special  Tobacco  Grower,  a  second  sample 
which  fully  met  its  guaranty  was  drawn  from  another  source. 

A  second  sample  of  Coe-Mortimer's  Top  Dressing  Manure 
1916  was  also  found  to  meet  its  guaranty.  The  same  is  true  of 
Royster's  Penguin  Ammoniated  Phosphate  as  appears  from  the 
analysis  in  the  table. 


Quality  of  the  Nitrogen. 

The  solubility  of  the  water-insoluble  nitrogen  in  all  factory 
mixtures  has  been  determined  by  the  permanganate  methods  of 
Jones  and  Street.  In  the  following  brands  the  presence  of 
inferior  forms  of  nitrogen  was  indicated  by  both  methods : 

T2520  Atlantic  Packing  Co.'s  Grain  Fertilizer. 

12783  Berkshire  Fertilizer  Co.'s  Grass  Special. 

12612  Berkshire  Fertilizer  Co.'s  Potato  and  Vegetable  Phosphate. 

12597  Berkshire  Fertilizer  Co.'s  Root  Fertilizer. 

12717  Coe-Mortimer  Co.'s  Tobacco  Special. 

12531  Lowell  Fertilizer  Co.'s  Potato  Manure. 

12849  New  England  Fertilizer  Co.'s  Corn  and  Grain  Fertilizer, 

12848  New  England  Fertilizer  Co.'s  Standard  Phosphate. 

13031  Rogers  &  Hubbard  Co.'s  Bone  Base  Soluble  Corn  and  General 
Crops. 


NITROGENOUS    SUPERPHOSPHATES    WITHOUT    POTASH,  75 

The  Berkshire  Fertilizer  Co.  explains  that  their  formulas  were 
calculated  to  furnish  the  full  amount  of  nitrogen  necessary  to 
meet  their  guaranties  in  available  form  without  counting  the 
nitrogen  in  garbage  tankage  which  was  added  as  a  conditioner 
or  dryer.  To  such  use  of  garbage  tankage  or  other  conditioner 
no  objection  is  made,  but  in  these  cases  the  formulas  did  not  meet 
the  guaranties  without  counting  in  the  inferior  nitrogen  of  the 
conditioner. 

Analyses  Needing  Special  Notice. 

12700,  Atlantic  Packing  Co.'s  Tobacco  Special  was  below  guar- 
anty in  nitrogen  and  far  above  it  in  available  phosphoric  acid. 
The  manufacturer  objected  that  this  did  not  fairly  represent  the 
composition  of  this  brand.  A  second  sample  of  this  brand  was 
therefore  drawn  and  analyzed,  12953,  which  fully  met  the 
guaranty. 

12778,  the  above  firm's  Top-Dresser,  was  deficient  in  nitrogen. 
The  manufacturer  showed  that  this  was  stock  carried  over  from 
the  previous  season.  Another  sample,  representing  the  present 
season's  output,  12986,  also  showed  a  slight  deficiency  of  nitrogen. 

13156,  Coe-Mortimer's  Top-Dressing  Manure,,  1916,  being 
found  deficient  in  available  phosphoric  acid,  a  portion  of  our 
sample  was  sent  to  the  manufacturer's  chemist  whose  analysis 
differs  from  ours  in  these  respects :

Total  phosphoric  acid 8.55  9.08 

Frequently  manufacturers  have  called  for  portions  of  our 
samples  for  their  own  test,  but  in  all  other  cases  so  far  as 
reported  their  results  and  ours  have  substantially  agreed.  We 
cannot  explain  the  discrepancy  in  this  case.

NITROGENOUS  SUPERPHOSPHATES  CONTAINING  POTASH. 

In  the  table  are  given   107  analyses  of  brands  belonging  to 
this  class.     (See  page  gs.)

The  amounts  of  potash  guaranteed  are  naturally  much  smaller 
than  before  the  war. 

Of  the  samples  drawn  by  the  station  agent

To  compare  the  relative  economy  of  purchase  of  goods  having 
these  different  guaranties  of  nitrogen  we  may  make  a  "valuation'* 
of  the  fertilizer  elements  guaranteed  in  each,  allowing  45  cents 
per  pound  for  nitrogen,  10  cents  for  "available"  phosphoric  acid 
and  30  cents  for  potash. 

This  has  been  done  in  the  case  of  each  brand,  the  valuation 
then  compared  with  the  average  cost  of  each  formula  having 
the  same  nitrogen  guaranty,  the  percentage  difference  between 
the  quoted  retail  price  calculated  and  the  weighted  average  deter- 
mined.    The  results  are  as  follows :

The  "percentage  difference"  represents  approximately  the  per- 
centage amount,  reckoned  on  the  cost  of  the  fertihzer  ingredients 
themselves,  which  covers  the  costs,  profits  and  losses  of  manu- 
facture and  selling. 

The  practical  lesson  taught  by  it  is  that  it  does  not  pay  the 
buyer  to  get  low  grade  goods  if  he  wishes  to  buy  a  fertilizer 
for  general  use.  The  ton  price  is  lower  but  the  plant  food  in 
them  costs  more. 

In  cases  where  he  wishes  to  use  a  relatively  small  amount  of 
nitrogen  with  a  larger  quantity  of  phosphoric  acid  on  a  special 
crop,  oats  for  example,  he  can  generally  save  money  by  buying 
a  small  amount  of  high  grade  fertilizer  and  using  with  it  a  proper 
amount  of  acid  phosphate,  if  he  does  not  find  it  even  more 
economical  to  buy  all  the  chemicals  unmixed  and  prepare  the 
mixture  himself.  The  economy  of  this  practice  must  be  largely 
determined  in  each  case  by  costs  of  the  chemicals  and  labor 
locally,  and  method  of  payment. 

Guaranties. 

Of  the  brands  sampled  by  the  station,  7  failed  to  meet  their 
guaranty  of  nitrogen,  4  failed  in  available  phosphoric  acid  and 
9  in  potash  while  two  were  deficient  in  both  nitrogen  and  potash. 
In  all  cases,  however,  except  those  named  below,  the  deficiency 
in  one  ingredient  was  fully  covered  in  money  value  by  the  excess 
of  another. 

In  five  brands  the  money  value  of  the  deficiencies  was  more 
than  one  dollar  per  ton,  valuing  nitrogen  at  45  cents,  available 
phosphoric  acid  at  10  cents  and  potash  at  30  cents  per  pound.

Quality  of  the  Nitrogen. 

The  solubility  of  the  water-insoluble  nitrogen  as  determined 

by  the  two  methods  in  use  (the  neutral  permanganate  and  alkaline 

permanganate  methods)  indicates  that  a  portion  of  the  organic 

nitrogen  is  of  inferior  agricultural  value  in  the  following  brands :

Analysis  requiring  Special  Notice. 
*  12628.  This  sample,  page  96,  contained  very  much  less  nitro- 
gen than  was  guaranteed  in  the  brand  which  it  was  supposed  to 
represent  and  also  contained  2.52  per  cent,  of  potash  which  was 
not  guaranteed  in  that  brand.  It  is  quite  certain  that  through 
some  error  the  sample  does  not  at  all  represent  the  brand  the 
name  of  which  it  bore. 

Borax  in  Fertilizers. 

Borax  is  known  to  occur  in  the  potash  salts  obtained  from 
Searles  Lake  in  California  and  it  has  been  proved  that  even 
rather  small  amounts  of  borax  in  a  fertilizer  may  be  poisonous 
to  crops. 

The  United  States  Department  of  Agriculture  prescribes  that 
no  fertilizer  shall  contain  more  than  two  pounds  of  borax  or 
its  equivalent  in  the  ton  unless  the  actual  amount  of  borax  is 
plainly  stated  on  the  package  or  its  tag. 

The  Maine  Department  of  Agriculture  through  its  Division 
of  Inspection  has  ruled  that  any  fertilizer  containing  an  appreci- 
able amount  of  borax  or  its  compounds  will  be  deemed  to  be 
adulterated. 

In  our  opinion  there  is  very  little  chance  that  any  dangerous 
amount  of  borax  will  be  found  in  fertilizers  hereafter.  Manu- 
facturers are  fully  aware  of  the  danger,  which  may  be  as  disas- 
trous to  their  business  as  to  that  of  their  customers.

MISCELLANEOUS    FERTILIZERS   AND    WASTES.  lOI 

The  average  composition  and  cost  per  ton  of  sheep  manure 
as  determined  from  these  analyses  are  as  follows : 

Nitrogen i.99 

Phosphoric  acid 1.63 

Potash 2.5s 

Cost  per  ton $48.00 

The  agricultural  value  of  fresh  manure  is  largely  in  the  organic 
matter  which  it  contains  in  forms  that  decay  quickly  and  in  its 
bacterial  life.  The  use  of  dry  sheep  manure  is  chiefly  in  green- 
house work  and  on  lawns. 

"WOOD  ASHES." 

In  the  table  are  given  21  analyses  of  material  sold  under  this 
name.  Six  of  the  samples  are  certainly  not  fairly  called  wood 
ashes.  12655  has  the  composition  of  lime-kiln  ashes  and  12147 
does  not  contain  even  as  much  potash  as  ordinary  lime-kiln  ashes. 

During  the  war,  wood  ashes  have  been  sold  on  the  "unit"  basis, 
a  unit  being  one  per  cent,  or  20  pounds.  The  price  this  year 
has  ranged  from  $6  to  $6.50  per  unit  or  from  30  to  325^  cents 
per  pound  of  potash  without  regard  to  the  lime  or  phosphoric 
acid  contained  in  the  ashes. 

The  higher  per  cent,  of  phosphoric  acid,  6.40,  contained  in 
the  ashes  sold  by  E.  E.  Dickinson  &  Co.,  12418,  is  explained  by 
the  fact  that  the  ashes  came  from  witch  hazel  brush.  The  fine 
twigs  carry  considerably  more  phosphoric  acid  than  does  mature 
wood.  With  reference  to  12102  and  12159  Mr.  Joynt  states  that 
none  of  the  other  cars  shipped  at  the  same  time  from  the  same 
storehouse  showed  less  than  5.6  per  cent,  of  potash.  Sample 
12102  was  drawn  by  the  director  personally  with  the  greatest 
care  to  take  portions  from  all  accessible  parts  of  the  car  and  the 
analysis  was  most  carefully  checked.

MISCELLANEOUS    FERTILIZERS    AND    WASTES.  103 

PEAT  AND  MUCK. 

12164  was  sent  by  M.  F.  McLaughlin,  Bridgeport,  12165  by 
L.  Peterson,  East  Hartford,  and  12146  by  T.  H.  Thorne,  super- 
intendent, New  Canaan. 

These  require  no  further  notice. 

The  samples  represented  by  the  first  three  analyses  in  the 
table  were  sent  by  Henry  H.  Witzke,  Fairfield.  They  are  from 
a  maple  swamp  in  which  the  peat  is  at  least  20  feet  deep.  The 
three  samples  were  taken  at  depths  of  6,  12  and  18  feet  respec- 
tively.    They  consist  of  peat  with  very  little  mixture  of  soil. 

12165  was  sent  with  the  question  whether  it  would  be  good 
on  sandy  land.  This  sample,  too,  is  a  rich  peat.  If  used  in 
large  amount  and  well  distributed  through  a  sandy  soil  it  would 
undoubtedly  improve  its  water-holding  power  though  of  very  little 
value  as  a  fertilizer.  The  nitrogen  of  peat  is  very  inert  being 
the  part  which  has  resisted  decay  and  solution. 

Peat  which  has  been  more  than  half  dried  makes  one  of  the 
best  absorbents  in  the  manure  trenches,  tends  to  prevent  loss  of 
ammonia  and  improves  the  manure. 

13359  is  stated  to  be  everglade  soil  taken  near  the  southern 
end  of  Lake  Okeechobee  in  Florida  on  which  sugar  cane  and 
vegetables  can  be  grown  very  successfully  without  the  use  of 
any  fertilizer. 

This  consists  of  about  equal  parts  of  mineral  matter  or  soil 
and  of  peat.  It  has  a  higher  per  cent,  of  nitrogen  than  any 
other  of  the  samples ;  probably  it  is  never  subject  to  drought  and 
may  grow  crops  for  a  time  without  fertihzers  or  manure.

The  plant  food  in  the  dried  kelp  and  dried  mussel  bed  is 
probably  quite  readily  available  to  crops.  Whether  either  can 
profitably  be  used  depends  altogether  on  the  cost  of  getting  out 
the  material  and  transporting  it.  Kelp  was  formerly  used  with 
profit  on  some  seashore  farms  where  it  was  abundant  and  the 
haul  to  the  land  was  short.  The  best  results  were  got  where  it 
was  hauled  at  once  to  the  land  and  immediately  plowed  in.  The 
same  probably  applies  to  channel  weed  13475. 

With  regard  to  13474  Mr.  Knapp  says  there  is  a  limitless 
quantity,  not  over  1000  feet  from  porous  land  needing  amend- 
ment. 

It  is  a  fine  material  not  unlike  ordinary  soil,  as  far  as  the 
analysis  indicates,  having  in  the  water-free  material  only  7.8  per 
cent,  of  organic  matter. 

The  percentages  of  nitrogen  and  phosphoric  acid  are  also  small. 
Marine  mud  hauled  out  in  the  fall  and  allowed  to  stand  over 
winter  has  been  found  to  have  considerable  value  as  an  amend- 
ment and  fertilizer.  It  cannot  be  recommended  as  certainly 
profitable  in  any  case  but  is  worth  a  trial  on  a  small  scale. 

VARIOUS  NITROGENOUS  WASTE  PRODUCTS. 
11818.  Sent  by  B.  W.  ElHs,  Co.  Agent,  Rockville.  This  is 
material  which  has  been  used  as  a  bird  food  and  as  such  sold 
for  about  $90  a  ton.  It  contained  6.98  per  cent,  of  nitrogen 
and  3.84  of  phosphoric  acid.  Probably  both  are  in  available 
form  and  if  so  the  price  would  not  be  more  nearly  prohibitive 
of  its  use  as  a  fertilizer  than  is  the  present  price  of  cotton  seed 
meal.
